Injection molding tools with micro/nano-meter pattern

摘要

The present invention relates to methods for embedded a micrometer and/or nanometer pattern into an injection molding tool. In a first main aspect, a micro/nanometer structured imprinting device is applied in, or on, an active surface so as to transfer the micro/nanometer patterned structure to the tool while the imprinting device is, at least partly, within a cavity of the injection molding tool. In a second main aspect, a base plate with a micro/nanometer structured pattern positioned on an upper part is positioned on the active surface within the tool, the lower part of the base plate facing the tool, the active surface receiving the base plate being non-planar on a macroscopic scale. Both aspects enable a simple and effective way of transferring the pattern, and the pattern may be transferred on the active working site of tool immediately prior to molding without the need for extensive preparations or remounting of the tool before performing the molding process.

1. A method for manufacturing a micro/nanometer-structured pattern in, or on, the active surface of an injection molding tool, the method comprising:
providing the injection molding tool; providing a micro/nanometer structured imprinting device having a structure to be imprinted in said tool; and applying the imprinting device in, or on, the said active surface so as to transfer the micro/nanometer patterned structure to the tool while the imprinting device is, at least partly, within a cavity of the injection molding tool, the imprinting device being removed before performing the molding process.
